A small sample of man-man flying saucers. Are we to believe that research and development ended in the 50s-60s?
“The Avro Canada VZ-9 Avrocar was a VTOL aircraft developed by Avro Canada as part of a secret U.S. military project carried out in the early years of the Cold War. The Avrocar intended to exploit the Coandă effect to provide lift and thrust from a single “turborotor” blowing exhaust out the rim of the disk-shaped aircraft. In the air, it would have resembled a flying saucer.” https://en.wikipedia.org/wiki/Avro_Canada_VZ-9_Avrocar
Viktor Schauberger’s Repulsine
“When the main electric engine is started, the Coanda effect begins to create a differential aerodynamic pressure between the outer and inner surface of the primary hull. At a higher speed, the vortex chamber becomes a type of high electrostatic generator due to the air particles, in high speed motion, acting as an electrical charge transporter. The Repulsin A will begin to glow due to strong ionization effect of the air. Now we have all the ingredients for a continuous and strong Aether flow along the main axis from the top to the bottom of the craft. The radial air pressure required for lifting 1 kg with the Coanda Effect is roughly 1.4 kg/cm2.” – Rob Arndt http://discaircraft.greyfalcon.us/Viktor%20Schauberger.htm
US2801058A Saucer-shaped aircraft
SAUCER-SHAPED AIRCRAFT Filed Dec. 6, I950 3 Sheets-Sheet 5 United ttes This invention relates to saucer-shaped aircraft and more particularly to vehicles having a round or circular body contour known as flying saucers. https://patents.google.com/patent/US2801058A/en
US3067967A Flying machine
Machine of the class described in which reducing the empty weight while maintaining the gross weight for increasing payload capacity does not result in reduced aerodynamic performance of the flying machine.
US3103324A High velocity high altitude v.t.o.l. aircraft
This invention relates to aircraft, and relates more particularly to aircraft capable of vertical ascent and descent during take-off and landing and of high altitude flight at supersonic velocities. It is a general object of the invention to provide vertical rising and descending aircraft characterized by their unique aerodynamically efficient design and by propelling, refrigerating and control systems for producing safe, efficient, supersonic, long range flight. The aircraft of the invention is designed not only for vertical ascent and descent to facilitate. landing and taking off at small fields or landing areas but also for long range flight at a Mach number of, say, 4, and at altitudes in the region of 100,000 ft. https://patents.google.com/patent/US3103324A/en
US3124323A Aircraft propulsion and control
This invention relates to aircraft and more particularly to an aircraft having a body structure and a downwardly directed propulsive nozzle having a mouth arranged to discharge at a multiplicity of positions distributed around a periphery on the underside of the structure and a further propulsive nozzle extending around a rear portion of the periphery of the structure. The aircraft derives propulsive thrust from the ejection of propulsive gas at high velocity through one or both of the propulsive nozzles. https://patents.google.com/patent/US3124323A/en
